Nolan Predicted All of his Villains Ahead of Time
There’s no better superhero trilogy than the Nolan-verse Batman. Before Batman Begins, the franchise was dead on account of George Clooney’s Bat-Nipples and Joel Schumachers fetish for neon, and Nolan’s grounded approach brought the concept of ‘gritty’ and realistic superhero films to the forefront. We owe him so much.
Though, he maintained that he only took it one film at a time, and had ideas of where he wanted the franchise to go, he’s said in numerous interviews that he wasn’t seeding his films for sequels, nor was he sure he was going to make a sequel to Batman Begins and The Dark Knight, until he had finished them and had a great story in mind.
That said, he did add in some things, such as the Joker card at the end of the first film, but there’s another instance of foreshadowing that even I missed on the first few watchings. When Bruce is giving a speech at the party, before Wayne manor is set ablaze, he refers to his guests as “two-faced friends,” which hints at the arrival of Harvey Dent in the next film.
There’s also a moment during The Dark Knight, where Bruce asks Lucious Fox how his new armour will work against dogs, only to be told that it’ll do fine against cats. Meow.
